What Does a Good Window Replacement Contract Look Like?

Contracts protect window contractors and their customers by managing expectations and setting the project’s terms and conditions. We list their key elements in this post.

Good Window Replacement

Contract Types

There are two common types of window replacement contracts:

1. Fixed-Price Contracts

These contracts have set deadlines and state the cost of materials, labor, permits, waste disposal and everything else involved in the project. They also indicate the penalties associated with delays. 

Fixed-price contracts are generally preferable because they clearly define the cost of the project. Furthermore, if the contractor fails to include other expenses they’ve paid for or went beyond the contract’s stated budget, they can’t ask you for reimbursement.

2. Time-and-Materials Contracts

These contracts have flexible deadlines and budgets. Their terms can be changed depending on the time and materials necessary for the project. Reputable roofers rarely or never issue a time-and-materials contract because of the uncertainty associated with it.

The Details of a Typical Window Contract

A well-written window replacement contract includes all standard details, including your contractor’s mailing address, phone number and email address. Furthermore, it includes the project’s overview and scope of work. 

A window replacement contract must include the final cost to be paid for the materials, labor and other expenses involved. The contract must also state the license number and liability insurance company covering the window contractor’s work.

The document should include the start date and deadline of the project, penalty amounts for delays, and the payment methods to be used. Lastly, it should state all termination clauses, liens, warranties and the contractor’s working hours.

"This crew was every thing they said. They showed up on time, did a professional job on the install. I was there and they answered every ?? I had. My mane concern was the sealing of the door being that it was on north side of the house. We could tell a big difference after they were done. Thank you Renewal by Andersen doors/ windows of Wyoming."
